Safety
2. Safety
2.1 Application of the compressor
To prevent unintentional application of the compressor, which could injure personnel or dam-
age equipment, the following must be observed:
• The compressor must only be used as a refrigeration compressor and within the oper-
ating limits specified in the manuals or in a written agreement with Johnson Controls
Denmark.
• HPC 100 compressors can as standard compressors be used with refrigerants R717
and R744. Please see the relevant operating limits diagrams in the
Engineering
manual .
• The compressors can be used with other refrigerants, but only following a written
agreement with Johnson Controls Denmark.
• HPC compressors may be used at a max. discharge pressure of 50 bar.
• Johnson Controls Denmark further accept no liability of any kind for damage to com-
pressor unit and plant parts caused by torsional oscillation or the like, which is attribut-
able to built-in VSD solutions initiated by the customer after delivery.
• ATEX : The compressor is approved for application in potentially explosive atmos-
pheres provided it is fitted with explosion-proof equipment. If it is ATEX approved, there
will be an EX name plate fixed on the unit. Please note that special non-sparking tools
must be used for all maintenance work on the compressor.
The compressor must not be used:
• to evacuate the refrigeration plant of air and moisture.
• to put the refrigeration plant under air pressure in view of a pressure testing.
• as an air compressor.
Warning!
Johnson Controls Denmark is not liable for injuries to personnel or damage to equipment re-
sulting from using the equipment for other purposes than the ones stated above.
2.2 Application of combustion engines
According to EN 378/ISO 5149, no other machinery should be installed in a refrigeration ma-
chine room. Some refrigerant types may, to a certain extent, be absorbed by the fuel in a com-
bustion engine, and when the contaminated fuel reaches the fuel pumps, the refrigerant will
“flash out” (separate) and react on the increased temperature and pressure by creating acids,
which will destroy the pumps. However, check with the local authorities as exemptions to this
rule may be granted.
